APPARATUS FOR PRODUCING TUBING FROM HOLLOW BILLETS.

SPECIFICATION forming part of Letters Patent No. 660,463, dated October 23, 1900.

Application filed April '7, 1898. Serial No. 676.839. (No model.)

To ctZZ whom, it may concern.-

Be it known that I, JOHN THOMAS RowLEY, a citizen of the United States, residing at Beaver Falls, in the county of Beaver, State of Pennsylvania, have invented or discovered certain new and useful Improvements in Apparatus for Producing Tubing from Hollow Billets, of which the following is a specification.

My invention relates to improvements in plevices for producing tubing from hollow bilets.

The object of my invention is to produce a machine adapted to form and finish tubing from hollow billets; and to this purpose my invention consists in the novel construction, combination, and arrangement of parts hereinafter set forth, reference being had to the accompanying drawings, which form a part of this specification, and in which like reference characters indicate like parts wherever they occur throughout the several views.

In the accompanying drawings, Figure l indicates a side elevation of my improved apparatus for producing tubing from hollow billets. same. Fig. 3 is a plan view of the same. Fig. 4: is a front elevation of the bracket and support for the billet. Fig. 5 is an end view showing one of the frames out of vertical alinement with the other frame.

Referring to said drawings, A and B are independent bed-plates or foundations, the upper surfaces or tops of which are concaved and slotted to receive the lower end of the independent frames 0 and D, arranged on said bed-plates immediately opposite each other. The said frames are adapted to be thrown out of vertical alinement with each other or to be angnlarly disposed to each other, as shown in Fig. 5,-by means of the adjustingbolts a a, the said foundations or bases being concaved in curvature to admit of this.

E is a large rope-sheave mounted on the shaft a,.which is journaled in bearings b, formed in a bracket 0, which projects from the side of said frames 0 and D, respectively. A gear-wheel d is also mounted on said shaft (1 and meshes with and transmits power to a larger gear-wheel e, mounted on shaft f, journaled in bearings f, formed in the sides of said frames 0 and D, respectively. Said last- Fig. 2 is an end elevation of the mentioned gear-wheel is rigidly secured to said shaft f, and a large drum or pulley F is also mounted on said shaft f, whereby motion is transmitted to the comparatively heavy continuous steel bands G G, which pass therearound and around a similar drum H, mounted on a shaft g, journaled in bearings 71., formed in the upper sides of said frames G and D, respectively. The said frames C and D are adapted to be angularly arranged with reference to each other for the purpose of producing a corresponding angular disposition in the bands G G. A large gear-wheel emeshes with and transmits power to the gear-wheel 1i, mounted on a shaft journaled in bearings it, formed in the sides of said frames C and D, respectively. The said gear-wheelt' meshes with and transmits power to a smaller gearwheel Z, mounted on the shaft m, journaled in bearings n, formed in the sides of said frames 0 and D, respectively. A guide or supporting pulley or roller 0 is also mounted on said last-mentioned shaft and is so arranged with reference to said steel bands G G as to impinge lightly against the inner sides of the same. It is obvious, however, that these pulleys need not be driven positively, but may be driven by the friction of the bands, the function of the same being merely to support the piece.

In the arrangement of my rolling-machine the supporting pulleys or rolls are respectively geared to be driven at high speed. The said rolls coincide in width with the said steel bands and may be of any size.

It will be observed that my improved rolling apparatus comprises duplicate parts independently geared, but driven by the rope or other suitable means operating over the sheaves and so arranged that the contiguous faces of the bands travel in opposite directions when the said frames are opposed to each other, as shown in, Fig. 1, whereby a hollow billet so, when heated and passed between said oppositely-moving bands,is given a rotary progressive movement. The rotary movement given said billet by the movement of the bands feeds the billet between the bands toward and over a mandrel y, thereby elongating the billet, enlarging the orifice therein, and giving the interior of the same a finished surface. The said mandrel y is secured in a bracket which is secured upon the sides of the frames C and D, as shown in Fig. 3, The billet a; is supported below by the guide or support g, which is secured upon the inner sides of the frame opposite the mandrel and in alinementtherewith.

The operation of my improved apparatus is as follows: A hollow billet {I}, being properly heated, is passed between the bands, as shown.

claim, and desire to secure by Letters Patent,

1. In an apparatus for rolling and finishing tubing from hollow billets, the combination of two oppositely-moving s! eel bands, the said bands being angularly disposed, means to operate the same, and support guides or rollers to keep the bands operative'ly against the billet fed between said bands, substantially as set forth.

2. In an apparatus for rolling and finishing tubing from hollow billets, the combination of two oppositely-moving steel bands, the said bands being angularly disposed, means to operate the same, support guides or rollers to keep the bands operatively against the billet fed between said bands, and a mandrel in alinement with said billet, substantially as set forth.

3. In an apparatus for rolling and finishing tubing from hollow billets, the combination of two angularly-disposed oppositely-moving steel bands adapted to operate over drums or pulleys, means to operate the same, guide pulleys or rolls to keep said bands up to the billet fed between them, means to operate the same, and means to adjust the angularity of the bands, substantially as set forth.

4. In an apparatus for rolling and Finishing tubing from hollowbillets, the combination of two angularly-disposed oppositely-moving steel bands, means to operate the same, supports or rolls to keep the bands up to the billet passing between them, and means to operate the same, substantially as set forth.

5. In an apparatus for rolling and finishing tubing from hollow billets, the combination of two angularly-disposed oppositely-moving steel bands, means to operate the same, supports or rolls to maintain the bands against the billet fed between them, means to operate the same, means to support the billet in its passage between said bands, and a mandrel in alinement with said billet, substantially as set forth.

In testimony whereof I have hereunto affixed my signature in the presence of two subscribing witnesses.

JOHN THOMAS ROWLEY.
